Vacuum line routing help please...

I've searched and haven't been able to find the answer I'm looking for. I looked at realoem and didn't see it. Sorry if I overlooked it.
Where does the vacuum line from the fuel pressure regulator connect?
Thanks if you can help.

Fuel pressure regulator is Part number 3. Only one line in. Where part number 16 is the vacuum line, so that should be the connect point. Everything else goes on top of the FPR. I could be wrong, but pretty sure that's correct. Maybe one of the other guys can double check me for my own benefit and yours.

Thanks for the response. I didn't word my question correctly. I have the FPR connected to the vacuum line. Where does the FPR get it's vacuum from? Where does #17 lead to?
I guess I'm showing that I'm still leaning my car's systems.

Thanks again.

a port on the manifold??

you should see your emissions sticker under the hood, and the fpr is either on the fuel rail or under the car. regardless, the vac lines are all on the bottom where they are out of (ready) sight. very german.

I'm on the road Or I'd try to look it up for you but the diagrams on OEM I remember one of them being the full vacuum line system perhaps it's on that one?

You're right about that! I finally was able to follow the routing from the FPR under the car.
